Risk for Peritoneal Mesothelioma Keeps Rising Decades After Exposure

risk for peritoneal mesothelioma

Pleural mesothelioma risk may level off over several decades, but the risk for peritoneal mesothelioma never goes down. That is the conclusion of researchers at Italy’s University of Eastern Piedmont. It is based on data from more than 50,000 asbestos-exposed Italian workers.   More than 40 years after asbestos exposure, the workers’ risk for peritoneal mesothelioma continued to rise. Calculating Mesothelioma Rates Over Time Asbestos is the primary cause of all types of malignant mesothelioma. Even short-term asbestos exposure raises the risk for peritoneal mesothelioma and pleural mesothelioma. Peritoneal mesothelioma occurs in the lining of the abdomen. Pleural mesothelioma tumors start on the lining around the lungs.  If asbestos fibers are inhaled or swallowed, they embed themselves in these linings. This … Continue reading Risk for Peritoneal Mesothelioma Keeps Rising Decades After Exposure »

Mesothelioma Risk From Home Renovation in The Spotlight

mesothelioma risk from home renovation

The case of an Australian man is highlighting the mesothelioma risk from home renovation when asbestos is present.  Forty-two year old Matthew Werfel recently won a lawsuit against Amaca, the asbestos producer previously known as James Hardie. The company manufactured the asbestos-containing cement sheets that led to Werfel’s pleural mesothelioma. The record $3 million payout is an expensive warning to other DIY homeowners about the potential mesothelioma risk from home renovation. Asbestos in Construction Products Asbestos is a mineral that has to be mined from the ground. As early as the 1930’s, companies like James Hardie recognized its potential value as a construction material. Asbestos is strong, plentiful and resistant to heat and corrosion. It was used for decades to … Continue reading Mesothelioma Risk From Home Renovation in The Spotlight »

Low-Dose CT Screening May Delay Mesothelioma Deaths

low-dose ct screening for meosthelioma

The results of a long-term national study suggest that low-dose CT screening might prevent – or at least delay – deaths from pleural mesothelioma.  The National Lung Screening Trial included more than 53,000 lung cancer patients. Researchers released the first results in 2011 after more than six years of study. The recent follow-up results reflect more than 12 years of data on low-dose CT screening. They show that, in many cases, screening lung cancer patients for at least three years delayed their deaths for more than a decade.  Pleural Mesothelioma and Lung Cancer Pleural mesothelioma is not the same thing as lung cancer. Mesothelioma starts on the lining around the lungs (pleura), rather than in the lung tissue itself.  But … Continue reading Low-Dose CT Screening May Delay Mesothelioma Deaths »

Study Highlights Link Between Mesothelioma Incidence and Ovarian Cancer

mesothelioma incidence and ovarian cancer

New research shows ovarian cancer rates are highest in states with the highest mesothelioma incidence. Researchers say it is because both are linked to the carcinogen asbestos. Scientists have known since as early as the 1950s that asbestos causes cancer. Malignant mesothelioma is the cancer most commonly associated with asbestos exposure. But women with a history of asbestos exposure face a higher risk of ovarian cancer, too.  The new CDC study is a reminder that a higher mesothelioma incidence is not the only threat from asbestos. Asbestos and Mesothelioma Incidence Before asbestos was linked to mesothelioma, it was a popular insulator and building product additive. Most US buildings constructed before the 1980s contain some asbestos. The asbestos in these buildings … Continue reading Study Highlights Link Between Mesothelioma Incidence and Ovarian Cancer »

Radiation Exposure Alone Unlikely to Cause Mesothelioma

radiation exposure in shipyards

A new study finds that low-dose occupational radiation exposure is unlikely to cause mesothelioma by itself. Instead, the study confirms what scientists have suspected for at least 60 years: The primary cause of mesothelioma is almost always asbestos.  The goal of the study was to see if radiation exposure by itself raises the risk for mesothelioma. Researchers analyzed three groups of people exposed to radiation on the job.   After reviewing more than 50 years worth of records, the team found that some workers were more likely than others to get malignant mesothelioma. But these were not the workers with the most radiation exposure. Radiation, Asbestos, and Mesothelioma A team of epidemiologists, cancer specialists, and radiation experts ran the new study. … Continue reading Radiation Exposure Alone Unlikely to Cause Mesothelioma »

Evaluating Mesothelioma Symptoms: New Tool Makes it Easier

evaluating mesothelioma symptoms

Evaluating mesothelioma symptoms is an important step in planning treatment for asbestos cancer. But researchers at a top US cancer center say it is hard to do a thorough job using current tools. That’s why doctors at MD Anderson have developed their own method for evaluating mesothelioma symptoms. They made some mesothelioma-specific additions to an existing cancer symptom evaluation system. Tests on more than 200 mesothelioma patients show the method works well and is easy to use. The developers hope doctors can use it to design better mesothelioma treatment plans. The Importance of Evaluating Mesothelioma Symptoms When a patient receives a mesothelioma diagnosis, the next step is evaluating mesothelioma symptoms. This process can help give the doctor valuable information about … Continue reading Evaluating Mesothelioma Symptoms: New Tool Makes it Easier »

Exposed to Asbestos? Lung Fluid Test May Waste Valuable Time

exposed to asbestos worker

If you have been exposed to asbestos and your doctor sees a mesothelioma tumor on your CT scan, it may be a waste of time to do a lung fluid test, too. Many different types of cancer cause excess lung fluid or pleural effusions. Looking for cancer cells in pleural effusions is one of the ways doctors test for cancers like pleural mesothelioma. This is called effusion cytology. But a new study says this test may not be very reliable for people with malignant mesothelioma. If other factors point to mesothelioma, they say it makes more sense to skip effusion cytology and go straight to a biopsy. Mesothelioma Develops in People Exposed to Asbestos Pleural mesothelioma is a type of … Continue reading Exposed to Asbestos? Lung Fluid Test May Waste Valuable Time »

Flaxseed Compound May Help Prevent Malignant Mesothelioma and Asbestosis

prevent malignant mesothelioma with flaxseed compound?

There is new evidence that a compound found in flaxseeds may help prevent malignant mesothelioma and other asbestos-related diseases. The compound is an anti-inflammatory which appears to calm down the overactive immune system after asbestos exposure in mice. Inflammation has long been considered a key factor in the development of mesothelioma. Scientists are hopeful that preventing it may also prevent malignant mesothelioma. Inflammatory Response to Asbestos Exposure Asbestos is a group of naturally-occuring minerals that cause cancer in people and animals. When a person accidentally breathes in or swallows asbestos fibers, they trigger an inflammatory response that can last for years. White blood cells flock to the area and damaging free radicals are produced. Over time, some cells may become … Continue reading Flaxseed Compound May Help Prevent Malignant Mesothelioma and Asbestosis »

Risk for Mesothelioma Does Not Decline After Asbestos Exposure Stops

Asbestos worker faces risk for mesothelioma

A new report contains some disappointing news for former asbestos workers: The risk for mesothelioma does not go down when asbestos exposure stops. A team of US and Italian researchers reached that conclusion after combing the medical literature for studies on the risk for mesothelioma. Although the risk for several other cancers declines when the person is no longer in contact with the carcinogen, the study shows this does not apply to asbestos cancer. Asbestos Increases Mesothelioma Risk Asbestos is the primary cause of mesothelioma. It is a naturally-occurring mineral that is resistant to corrosion, does not burn, and makes an excellent insulator. Malignant mesothelioma was virtually unheard of until people started mining and using asbestos in industry. Since then, … Continue reading Risk for Mesothelioma Does Not Decline After Asbestos Exposure Stops »

Risk of Dying from Mesothelioma Varies by Type, Study Shows

Risk of dying from mesothelioma

The risk of dying from mesothelioma rises and gradually falls  in the decades after exposure for most, but not all, types of asbestos cancer. New research shows those peaks and valleys can vary based on a number of factors. Public health researchers from across Italy recently published their findings on asbestos workers’ risk of dying from mesothelioma. They suggest that the lifetime risk of dying from peritoneal mesothelioma stays high, even after the risk of death from pleural mesothelioma and lung cancer begins to drop off. Quantifying the Risk of Dying from Mesothelioma Asbestos is the primary cause of all three types of mesothelioma: pleural, peritoneal, and pericardial. Pleural mesothelioma is the most common asbestos-related cancer. Pleural tumors start on … Continue reading Risk of Dying from Mesothelioma Varies by Type, Study Shows »
